FILE - In this Feb. 14, 2013 file photo the cruise ship Carnival Triumph is towed into Mobile Bay near Dauphin Island, Ala., Thursday, Feb. 14, 2013. Want to know about a ship's track record for being clean? Want to assess how good or sanitary the food is? It's not that easy to find, in part because there's no one entity or country that oversees or regulates the industry with its fleet of ships that are like mini cities floating at sea. In the case of Carnival Cruise Lines, the owner of the Carnival Triumph that spent days in the Gulf of Mexico disabled after an engine fire, vacationers looking up information about the ship before boarding would have found mostly clean marks and few red flags.
